VAPOR-LAMP.

To all whom, t may concern:

Be it known that I, CLARENCE T. EWARD, a citizen of the United States, residing at Greensburg, in the county of Decatur and State of Indiana, have invented -a new and useful Vapor-Lamp, of which the following is a specification.

In the so-called vapor lamps, that is, those employing gasoline or the like for illuininant, which gasoline is vaporized before being burnt, an objection arises in igniting the lamps, because of the fact that the vaporizer must Yfirst bo heated to vaporize the fuel before the same can be employed, and so far as I am aware this has required either a separate torch or the employment of a preliininary heater that uses the gas or vapor which collects in the top of the reservoir. The former means is unsatisfactory, and the latter is not always effective, besides where the gasoline `is piped to the lamp any distance, the use of the same is iinpiacticable.

The present invention relates to the above class of lamps, and the particular object is to provide a novel, simple and entirely effective torch or heater that will employ the ordinary illuininant used for the lamp, will either effect a rapid preliminary heating oi the vaporizer or will maintain the saine at all times in condition for instant use, may be made to a'ct as an igniter foi' the lamp, is exceedingly inexpensive to manufacture and operate, and may be employed in connection with a variety of types of lamps of the above character.

The preferred embodiment of the invention is illustrated in the accompanying` drawing, wherein D Figure 1 is a perspective view of a lamp, with the improved device associated therewith. Fig. 2 is longitudinal sectional view on an enlarged scale through the vapori zing mechanism. Fig. 3 is a detail perspective view of a portion of the saine. Fig. 4 is a horizontal sectional view on the line Li-ll of Fig. 2.

Similar reference numerals designate corresponding parts in all the figures of the drawing. I

A hanging lamp is illustrated, comprising a pair of depending arms 5 and 6, one of which as 5 constitutes a fuel supply conduit. Suspended from these arms is a bracket 7 supporting a main burner 8, which may be of any desired or well known type. Connecting the lower ends of the arms 5 and 6 `the supply conduit 5.

is a vaporizer and air mixer, the vaporizer consisting of a tubo 9 that is disposed horizontally across and over thc main burner being connected through a coupling 1() with A suitable needle valve 11 controls the passage of the fuel to the vaporizer tube. Said tube 9 has its dischargel end associated with the air mixer 12, and the mixer is in turn connected with the main burner through a tubular arm 13 of the bracket 7. So far as thus described, the structure is well known to the art, and may bc varied without in any manner affecting thoI invention.

Connected to the fuel supply conduit 5 through the coupling 1() is a branch conduit 1li, in the form of an elbow that extends bcneath the main vaporizei tube 9, and has connected thereto a diminutive vaporizer, comprising a body 15, having an indirect passageway 16 therebetween, which passageway is in communication with the branch conduit 14. A needle valve 17 screwed into the body 15 controls the supply of fuel through the said passageway 16. A torch or heater burner in the form of a-sleeve 1S is carried by the body 15, and is located at one side of the saine, said burner sleeve being vertically disposed and arranged beneath the main vaporizer tube 9, or in other words, between said tube and the main burner, though preferably, slightly to one sido of the latter.

. I/Vithin the sleeve is mounted a suitable wire gauze or other perforate diaphragm 19. Suspended from the body 15, and communi- -cating with the passageway 16 is a vapor conduit 20, having a discharge nozzle 21 provided with an upwardly turned outlet orifice 22, located beneath and in spaced relation to the lower end of the burner tube 1S.

The structure, as thus described, may be employed in a variety of ways. For instance, if it is desired to effect a preliminary heating of the main vaporizer 9 at the time the lamp is to be lighted, the valve 1.7 is opened to permit the fuel to enter the diminutive vaporizer and this vaporizer is small enough to be heated by a match. The vapor therefrom passing through the conduit 2(),-is discharged through tlie orifice 22, and mixing with the air, asses through the burner sleeve 1S. It is then lighted above the diahragm 19, and the flame thereof not only lieats the main vaporizer 9, but also maintains the diminutive vaporizer at an operative temperature. As soon as the main TOO vaporizer 9 has been properly heated, the

valve 1l is opened to allow the fuel to pass thereinto, and the vapor mixed with the air in the mixer 12, passes to the main burner, l which in turn, heats the main vaporizer 9. 'Vhen the lamp is in operation, the diminutive vaporizer may be cut off if desired. l Under ordinary conditions, however, the diminutive vaporizer may be liept in operation, and as it consumes but a very small l amount of fuel, its employment in this manl, ner is believed to be advantageous, as the l main vaporizer is then kept heated at all l times, and is ready for instant use. Consei quently to light the lamp, all that is necessary is to open the valve ll, whereupon the l fuel will be vaporized, will be mixed with l the air, and will pass to the main burner. 1 The iirstof this vapor will pass through the burner, and coming into contact with the l flame of the torch burner will becoi'ne ignited, l thereby igniting the lamp. It will thus be l seen that this diminutive vaporiZer and torch burner may be made to perform three distinct functions. That is to say, the l burner 19 heats the diminutive vaporizer, l heats the main vaporizer, and acts as ani igniter. l

It will be apparent that the structure is 5 very simple, that it can be easily and cheaply manufactured, and that it may be combined with various types of lamps of the character disclosed.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction'may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

I'Iaving thus fully described my invention, what I claim as new, and desire to secure byV l Aetters Patent, is f l. In a vapor lamp, the combination with l a main burner, of a fuel supply conduit, a main vaporizer heated by the main burner and connected thereto and to the supply conduit, a stationary diminutive vaporizer, a connection between the same and the supply conduit, a torch burner supplied by the `diminutive vaporizer and associated with the main vaporizer and the main burner, constituting heating means for the former and an igniter for the latter, said torch burner also constituting a heater for the diminutive vaporizer and being arranged so that it may burn continuously to constitute a pilot light for the main burner and a continuous heater for the main vaporizer, and a valve for controlling the passage of fuel into the main vaporizer, said valve being located in the conduit between the main vaporizcr and the connection of thediminutive vaporizer with said conduit.

2. In a vapor lamp, the combination with a main burner, of a fuel supply conduit, a main vaporizer connected to the fuel supply conduit and extending above the main `burner and heated thereby, a stationary diminutive vaporizer, a branch tube connecting the supply conduit and the diminutive vaporizer, a controlling valve located in the branch tube, a torch burner supplied by the diminutive vaporizer and located below the main vaporizer and above the main burner, constituting heating means for theformer and an igniter for the latter, said torch burner also constituting a heater for the diminutive vaporizer and being disposed to constitute a pilot light for the main burner, and a controlling valve located in 'the fuel supply conduit between the branch tube and the main vaporizer.

In testimony, that I claim the foregoing as my own, I have hereto allixed my signature in the presence of two witnesses.
